00:15

outside world and no we don't mean running into your math teacher at the

00:18

grocery store for example we can use addition to figure out how much our

00:22

groceries will cost and subtraction if we need to put back a few tubs of ice [a woman carrying lots of tubs of ice cream]

00:25

cream sometimes parents just don't understand the value of having a spare

00:29

20 liters of ice cream lying around another thing we might see in the real

00:32

world array an array is an arrangement of objects into rows and columns you

00:37

might have seen an array of dots with four rows and five columns as a way to [green dots in 4 rows and 5 columns]

00:41

illustrate the number 20 there are plenty of other kinds of arrays we can

00:44

find in the real world one common example of an array is a carton of a

00:48

dozen eggs this carton has two rows and six columns which helps us keep all 12 [a carton of 12 eggs depicting an array]

00:52

eggs in the protected comfort of an array nice and snug another non

three rows and five columns however unlike our carton of eggs there isn't a

01:13

big number on the side of our tin telling us how many muffins it contains

01:16

since we can't see a number anywhere we should just throw out the tin and stick [a man throwing out a tin of muffins in the trash]

01:20

with foods that are more clearly labeled not so fast we can use a bit of math to

01:24

figure it out we see that each row contains five muffins and we see that

01:28

there are also three rows now if we multiply 5 by 3 we see the tin contains [multiplication of 5 times 3 for an array of muffins]

01:33

a total of fifteen muffins and luckily the garbage contains zero no ones

01:37

favorite flavor of muffin is trash well except Mr. Raccoon over here [a raccoon eating a muffin in the trash]
